The mean annual daily duration of bright sunshine is three hours and 42 minutes. There are two distinct local weather phenomenon, marked downslope lee winds caused by the proximity of the Pennines, leading to super geostrophic winds which can reach in excess of 70 mph, most commonly in winter and spring. In the winter, the presence of a subsidence inversion between the Pennines and the North Yorks Moors can allow dense, persistent fog to form that can last for several days.
